javascript - 加载 javascript/css 时消除页面闪烁

Question

我尝试将内联 javascript 代码放在之后</body>，但没有帮助。

HTML 代码：

<html>  
<head>
        <meta charset="UTF-8"/>
        <title> Foodstant Delivery </title>

        <link rel="stylesheet" type="text/css" media="screen" href="testCSS.css" />
        <link rel="stylesheet" type="text/css" href="jquery.booklet.1.4.0.css" media="screen" />

        <script type="text/javascript" src="scripts/jquery-1.7.2.js"></script>
        <script type="text/javascript" src="scripts/jquery-ui.min.js"> </script>

在加载 js 之前使用 css 将 body 的可见性设置设置为隐藏，然后使用 jquery 删除带有 js onload 的属性。CSS：

  body { visibility: hidden;}

javascript:

  $().ready(function(){ $("body").css({visibility:'visible'})});

如果我正确理解了这个问题，请将其放入 testCSS.css ...

#numb1 { visibility:hidden; }

或者...

#numb1 { display:none; }

哪个更让你高兴。

这样做会在页面显示之前隐藏 numb1 元素。你所做的让页面在隐藏它然后淡入之前加载，所以它是短暂可见的。
